LAME MT MP3 Encoding & Cinebench 3D Rendering
In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a very popular scenario that many end users work with on a day-to-day basis to provide portability and storage of their digital audio content. In this test, we created our own 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes.
Processing times are recorded below. Once again, shorter times equate to better performance.
In our single-threaded LAME MP3 encoding tests, the processor with the highest clock is king, and in this case its the XPS 710 H2C. The story is slightly more complicated in the multi-threaded test. While the XPS system retains first place, we see our custom quad-core rig (2.66GHz) losing to the two higher clocked X6800 (2.93GHz) machines. This indicates that the 3rd and 4th cores are not being utilized to their fullest.
The Cinebench 2003 benchmark is an OpenGL 3D rendering performance test, based on the commercially available Cinema 4D application. This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The time it took each test system to render the entire scene is represented in the graph below (listed in seconds).
If your into 3D rendering, then the more cores/processors the better. The XPS 710 H2C and our own custom quad-core machine take 1st and 2nd respectively. The XPS' multi-threaded score is half that of our Athlon FX-62 system. In single-threaded mode, it's all about processor IPC and clock speed.
